When addressing the erroneous doctrine of Once Saved Always Saved, one will often hear, "All means ALL." This statement is usually made in reference to two Scriptures.

"And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day." John 6:39-40
Jesus describes those who will be raised on the last day in two ways:
They have been given to Him by the Father = They have seen Jesus and believe on Him.
